Abstract

Systems and method for enhancing measurement performances by a User Equipment (UE) by reducing a measurement period. In some embodiments, a method performed by the UE for using a Pre-Configured Measurement Gap Pattern (PMGP) comprises a step of determining a status of the PMGP based on one or more criteria and a step of performing a measurement either using a gap within the PMGP or without using a gap within the PMGP, based on the determined status of the PMGP.

         13 . The method of  claim 1 , wherein performing the measurement comprises performing the measurement during a gap within the PMGP responsive to the determined status of the PMGP being activated. 
     
     
         14 . The method of  claim 1 , wherein performing the measurement comprises performing the measurement without using a gap in the PMGP responsive to the determined status of the PMGP being deactivated. 
     
     
         15 . The method of  claim 1 , wherein the one or more criteria is pre-defined or configurable by a network node in communication with the UE. 
     
     
         16 . The method of  claim 1 , wherein determining the status of the PMGP comprises receiving a message from a network node in communication with the UE, the message indicating the status of the PMGP. 
     
     
         17 . A method performed by a User Equipment, UE, for using a Pre-Configured Measurement Gap Pattern, PMGP, the method comprising:
 receiving a PMGP status indication from a network node;   determining a status of the PMGP based on the received PMGP status indication; and   performing a measurement either using a gap within the PMGP or without using a gap within the PMGP, based on the determined status of the PMGP.
